Hello, I am working on a fresh install of OOD on Ubuntu 22.04 (migrating from CentOS 7). All dependencies seem to be installed but running into the following issue:

Those errors are hard to diagnose because I’m never quite sure if they matter or not and I don’t see anything there that’s really fatal.
I’d look for these 2 things:
- What is the behavior you see from the client?
- When you start this job up - get a shell session to the compute node if you can. Issue
ps and so on to see if everything is infact up and running like
Thank you for the quick response.
- I see a “Failed to connect to server” message on the noVNC page
- Here is the output I get on the node where this job is running:

OK - before you do what I’ve laid out below I want do to this quick spot check.
- have you enabled
ood_portal.yml. You need to if you haven’t.
- Be sure you’ve got the correct
Once you’ve done those and it still isn’t working - we have to debug more in Chrome because you need to set this feature that only chrome has:
- Open up the developer tools in Chrome
- Navigate to the options (the cog near the top of the developer tools)
- check this box.
With this enabled
- open your dev tools on the interactive sessions page
- when you click the ‘connect to desktop’ button - dev tools should still be open on the new tab
- on the new tab (that presumably says ‘failed to connect to server’) look at the network tab for anything that’s failed.
here is what I have in the ood_portal.yml
#ONLY FOR TESTING
- 'AuthType Basic'
- 'AuthName "Open OnDemand"'
- 'AuthBasicProvider PAM'
- 'AuthPAMService ood'
- 'Require valid-user'
After changing the chrome setting I see the following error on the “console” nothing for the “network” tab:
websock.js:231 WebSocket connection to 'ws://clusterhn.cluster.pssclabs.com/rnode/n006.cluster.pssclabs.com/50812/websockify' failed:

n006.cluster.pssclabs.com is the hostname, but your
'[\w.-]+\.cluster\.com') doesn’t account for the
I changed the regex to:
But I am still seeing the same error.
Be sure to bounce apache for it to take affect. Plus in the network tab you should see
403 forbidden for this request specifically (if it’s still the same issue).
Ok great. That seems to have done the trick.
Thank you so much for your help.
